Acoustic investigations of the ZrV2–H system
2005
Abstract Elastic modulus and internal friction of the ZrV 2 H x system have been measured by the method of low-frequency acoustics (∼1 kHz) in a wide range of hydrogen concentrations (0 ≤ x ≤ 6) and temperatures (65 K T 2 compound towards high temperatures and leads to its suppression. An anomaly of the elastic modulus in the concentration range 0.7 x ≤ 6 with a corresponding peak of the internal friction was detected at a temperature of ∼200 K, characteristic of the phase transition. The relaxation peak of the internal friction observed above 200 K is caused by dissipation of elastic energy on interphase boundaries.
